B2610
STEERING COLUMN: POWER TILT AND POWER TELESCOPIC STEERING COLUMN SYSTEM: B2610: Tilt Position Sensor or Tilt Motor Circuit Malfunction
B2610 - Tilt Position Sensor or Tilt Motor Circuit Malfunction
DESCRIPTION
The tilt motor is operated by the power source voltage supplied from the multiplex tilt and telescopic ECU and tilts the steering column up and down. The tilt position sensor (hall IC) in the tilt motor detects the tilt angle of the steering column and outputs a signal to the CPU based on that tilt.
HINT
Limit positions can be confirmed on the screen of the Techstream.
WIRING DIAGRAM
INSPECTION PROCEDURE
PROCEDURE
1. PERFORM ACTIVE TEST USING THE TECHSTREAM (TILT UP/DOWN)
(a) Select the Active Test, use the Techstream to generate a control command, and then check the tilt up/down operation.
Tilt & Telescopic
Result
B -- CHECK HARNESS AND CONNECTOR (MULTIPLEX TILT AND TELESCOPIC ECU - TILT POSITION SENSOR)
A -- Continue to next step.
2. CHECK HARNESS AND CONNECTOR (MULTIPLEX TILT AND TELESCOPIC ECU - TILT MOTOR)
(a) Disconnect the L34 multiplex tilt and telescopic ECU connector.
(b) Disconnect the L26 tilt motor connector.
(c) Measure the resistance according to the value(s) in the table below.
Standard resistance:
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.
3. INSPECT TILT MOTOR
(a) Apply the 12 V battery voltage to the tilt motor connector. Then check the steering wheel tilt operation.
OK:
NG -- REPLACE STEERING COLUMN ASSEMBLY Removal
OK -- REPLACE MULTIPLEX TILT AND TELESCOPIC ECU Removal
4. CHECK HARNESS AND CONNECTOR (MULTIPLEX TILT AND TELESCOPIC ECU - TILT POSITION SENSOR)
(a) Disconnect the L34 multiplex tilt and telescopic ECU connector.
(b) Disconnect the L26 tilt motor connector.
(c) Measure the resistance according to the value(s) in the table below.
Standard resistance:
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.
5. CHECK HARNESS AND CONNECTOR (MULTIPLEX TILT AND TELESCOPIC ECU - BODY GROUND)
(a) Measure the resistance according to the value(s) in the table below.
Standard resistance:
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.
6. CHECK MULTIPLEX TILT AND TELESCOPIC ECU (VCI, TIS TERMINAL VOLTAGE)
(a) Reconnect the L34 multiplex tilt and telescopic ECU connector.
(b) Measure the voltage according to the value(s) in the table below.
Standard voltage:
NG -- REPLACE MULTIPLEX TILT AND TELESCOPIC ECU Removal
OK -- Continue to next step.
7. CHECK TILT POSITION SENSOR
(a) Reconnect the L26 tilt motor connector.
(b) Measure the voltage according to the value(s) in the table below.
Standard voltage:
NG -- REPLACE STEERING COLUMN ASSEMBLY Removal
OK -- REPLACE MULTIPLEX TILT AND TELESCOPIC ECU Removal
